Want proof of just how much app-based solutions can disrupt established businesses? Try the fact that Uber, the Android- and iOS-based alternative to traditional taxi services, has just been valued at $17 billion.

The valuation comes on the back of a new round of venture funding for the 5-year-old company, which saw investors pour in another $1.2 billion. This makes Uber one of the most valuable startups in tech history.

One of the standard features on handsets that many of us heavily depend upon is text enlargement, on many dumb-phones it’s extremely easy to make your font size larger, but it’s proving to be considerably more difficult on smartphones, owing to the large amount of settings currently available.

However, it’s not as hard as you may think.

Theme Showcase, the powerful customization engine that’s baked into CyanogenMod, will soon be available from Google Play. Its release will allow those who don’t use CyanogenMod custom ROMs to take advantage of its theming features, such as the ability to apply different fonts, icons, wallpapers, and even boot logos.

There are plenty of positive things to say HTC’s nifty DotView case for the One M8, but its lack of support for third-party notifications isn’t one of them. Fortunately, those with a rooted device can now take advantage of an unofficial tweak to change this themselves.

If you’re a Flickr user you might be annoyed by Yahoo’s latest power play, which removes third party logins — meaning that from June 30 you’ll no longer be able to log in to your account using your Facebook or Google ID.

Yahoo claims that it’s so that the service can offer “the best personalized experience to everyone,” but it seems a pretty shameless way of getting users to sign up for Yahoo accounts (which you’ll now need to sign up to, or keeping using, the service). While Yahoo announced that this would be happening earlier this year, this is the first time we’ve had an actual date to put with the report.
